I HAVE been busted...let me tell you, its not fun...
#1 reason (IMO): DRAMA
that means ANYONE who knows about your grow, can and will, use it against you.
Heres a Scenario for you....
You live in a house in the middle of nowhere, and you rent the basement from your gf's best friends mother(who so happens to be a huge pothead/alcoholic). after living there you realize that you could be growing allota pot in that basement, and the owner of the house says that i can pay her my rent in buds that i produce...ok sounds great right...well wrong...already to many people know about it...
ONE DAY, im out and about in town(not at the house) and, Her oldest daughter called the police and told them everyhting because she was in an argument with her mother......now think about that for a second......she called the police and busted her own mothers grow operation IN HER OWN BASEMENT....why? because people are unpredictable, and people are JEALOUS, and want what you have. This bitch had the BALLS to go down in the basement, and gather my bongs, my steamroller, and many ounces of jarred, curing buds(sharksbreath i believe), and then bring them to another location, then call the police from the house...all in about an hours time.
Its a damn good thing that i got a tip from my business partner(who so happened to be watching my property) that cops were in my basement, that allowed me to go into hiding untill i could negotiate the terms of my arrest/charges through my lawyer and the state troopers..in the end i had to man up and turn myself in. They ended up pulling over 50 plants out of the house, and confiscating the most expensive equipment.
MORAL OF THE STORY:
dont tell a single sole, if you do, all it takes is ONE BITCH ON HER FUCKEN PERIOD TO SEND YOU TO JAIL.
